The first two film soundtracks I ever had and listened to were on audio cassette tape. A copy of STAR WARS by John Williams and a copy of STAR TREK – THE MOTION PICTURE by Jerry Goldsmith. Pretty much “standard”, no exotic “origin story” for me I guess, very “mainstream” within the film score community, but those two scores, copied from an original cassette tape (STAR WARS) and and original LP (STAR TREK – THE MOTION PICTURE) were my first film scores and put me on the path.
